Constrain arc or circle to be concentric

The concentric constraint causes two arcs, circles, or ellipses to have the same center point. On the ribbon, click Sketch tab  Constrain panel  Concentric Constraint  . Click the first arc, circle, or ellipse. Click a second curve to be concentric to the first. Continue to place concentric constraints, or do one of the following to quit: …

Constrain line or ellipse to be collinear

The collinear constraint causes selected lines or ellipse axes to lie on the same line. On the ribbon, click Sketch tab  Constrain panel  Collinear Constraint  . Click the first line or ellipse axis. Click a second line or ellipse axis. Continue to place collinear constraints, or do one of the following to quit: Right-click, and select …

Apply coincident constraint

Use Coincident Constraint to constrain points to other geometries in 2D and 3D sketches. On the ribbon, click Sketch tab  Constrain panel  Coincident Constraint  . Click the point to constrain. Click the geometry to which the point is constrained. Continue to place coincident constraints, or do one of the following to quit: Right-click, and …

Constraints in sketches

Constraints are automatically applied as you sketch. The constraint symbol on the cursor shows the constraint type. Constraints prevent unwanted changes to a feature when dimensions are changed or referenced geometry is moved. You can add or edit constraints and dimensions to control sketch shape and size. Before you add constraints , …

Show or hide geometric constraints

To show or hide constraints for all active sketch geometry, select either Show All Constraints  or Hide All Constraints  in the status bar. Alternatively, press F8 or F9. To highlight constraints for selected geometry, click Sketch tab  Constrain panel  Constraint Settings General tab and select Show constraints for selected objects. When displayed, any constraint can be …
